Dy/dx=-2x+15
d2y/dx2=-2
Since the acceleration is a constant negative it has an absolute maximum value for y(x), thus it opens downward, as x decreases without bound as x approaches ±∞
I believe the answer is 12, I apologize now if this is incorrect!
how about monthly? well, there are 12 months in a year, so it will the compound cycle is 12, thus
Answer:
The inverse is -1/7(x+4)
Step-by-step explanation:
We have the function
y = -7x-4
To find the inverse, exchange x and y
x = -7y -4
Solve for y
Add 4 to each side
x+4 = -7y -4+4
x+4 = -7y
Divide each side by -7
-1/7(x+4) = -7y/-7
-1/7(x+4) = y
The inverse is -1/7(x+4)
ANSWER
B.
EXPLANATION
The formula for calculating the cost in t years is given by:
To determine the cost in t years for a gallon of milk, we substitute,
C=$4.25
and
r=10%=0.10
in to the above formula to obtain:
Simplify the parenthesis to get,
The correct choice is B.
